The present invention provides a method for producing a toner, the method including: preparing a wax dispersion liquid by cooling a wax solution, in which a wax is heated and dissolved or dispersed in an organic solvent, in a container so that a standard deviation σ of a temperature distribution between a center portion of the container and an inner wall of the container is 0.5 or less and the cooling rate is 2.0° C./min or more, to precipitate wax particles in the wax solution; forming toner base precursor particles by adding an aqueous phase containing resin fine particles into an oil phase containing at least the wax dispersion liquid, a colorant and a binder resin and mixing the oil phase and the aqueous phase with each other; and preparing toner base particles by removing the solvent from the toner base precursor particles.
A method for producing a toner which comprises toner base particles containing at least a colorant, a binder resin and a wax, the method comprising:
